I've never really messed with DAZ's 3rd 4th generation unimeshes meshes.
I'm use to SubD meshes. like Genesis.Rex,Rox's etc etc.

I remember from the old days that V1 Possetta had a vertice that was not welded togeather think it's around her gen's between her legs.
Jump to genesis there's a few vertices not welded think there in one of the forearms.
or maybe it's unwelded edges. I just know the mesh is off.

I found this out when I had genisis in zBrush posed and symmetry didn't work.
I don't have 3rd 4th generation unimeshes meshes loaded.
u could check any mesh with zBrushes symmetry.

But unwelded vertices would not cause me a lot of grief with game style meshes.
But unwelded vertices would cause SubD meshes a lot of grief in any app.
or unwelded edges.

I remember it was easy to have stacked edges in LW 7 if you didn't watch what you where doing.
LW 7 was what 3rd generation was finished in.

Poser Pro 14 with SubD's changed the game.

There's wing,hex ,blender all free maybe one would do or show what the other don't
